ABC America said juror B-29, who used her first name Maddy, was a 36-year-old Puerto Rican woman who is a nursing assistant and a mother of eight. They said she had recently moved to Florida from Chicago.

Mr Martin's mother Sybrina Fulton said: "It is devastating for my family to hear the comments from juror B-29, comments which we already knew in our hearts to be true, that George Zimmerman literally got away with murder."

Hostile backlash on social media

Last week, juror B-37, a mother of two who grew up in a military family, appeared on CNN with her face obscured. She said she believed Mr Zimmerman was "justified" in shooting Mr Martin during a confrontation in a gated community in central Florida.

She said she did not think Mr Zimmerman racially profiled Mr Martin and believed he attacked Mr Zimmerman first.

Shortly after the interview, which prompted a hostile backlash on social media, CNN said four other jurors released a statement distancing themselves from B-37's comments.

Juror B-29 agreed with juror B-37 that the case was never about race, despite accusations by the prosecution that Mr Zimmerman had profiled Mr Martin when he called police to report someone acting suspiciously in the community near Orlando.

Mr Zimmerman's lawyers said he acted in defence after Mr Martin started beating his head against a concrete sidewalk.

In the latest interview juror B-29 said: "George Zimmerman got away with murder, but you can't get away from God.

"And at the end of the day, he's going to have a lot of questions and answers he has to deal with... (but) the law couldn't prove it."

She revealed that when the jury began deliberations she initially favoured convicting Mr Zimmerman, saying: "I was the juror that was going to give them the hung jury. I fought to the end."

But, she said, on the second day of deliberations she realised there was not enough proof to convict Mr Zimmerman of murder or manslaughter under Florida law.

She said she did not think the case should have gone to trial, adding: "I felt like this was a publicity stunt."
